摘要
本文采用动态GPS仪 ,现场测试高速公路上车辆行驶的动态速度 ,并与高速公路各种平曲线半径相对照 ,寻找不同驾驶员在平曲线半径与行驶速度间的变化规律 ;在此基础上 ,再与现行《公路路线设计规范》上的平曲线半径 -设计速度相对比 。
By kinetic GPS technology The mobile steering speed of the vehicle is tested on expressway in locality, and the steering speed is compared with diversified curve's radii on the expressway, then the relation between radius and speed is found for different drivers Based on it, comparing the radius and velocity with those in the Design Specification for Highway Route,the propriety of curve's radii and the safety of steering vehicle on the expressway are analyzed.
